IPC: H04N19/90
Filed: 1996-04-09
Abstract: The present invention relates to a fractal image compression device and method. The image data is divided into a plurality of range blocks and domain blocks and the blocks are classified according to their attributes. The domain block having a minimum distortion error value is obtained for each range block, as are corresponding contractive transformation coefficients as follows. A noise sensitivity value for each pixel of the said range block is calculated. Each domain block assigned to the said range block is spatially reduced to the size of the said range block, and the coefficients of the contractive transformation function are calculated from the spatially reduced domain block and the said range block. The distortion error value is calculated using the said range block, the contractively transformed domain block and the noise sensitivities. Finally, the location of the domain block and the coefficients of the transformation function are stored.

Title: Refrigeration systems
Inventor: GEORGE STEPHEN DAVID JOHN
IPC: G05D23/19
Filed: 1996-08-10
Abstract: A refrigeration system is designed to use electricity independently of its requirement to maintain a storage compartment in a range of temperatures. The system stores cold in a cold store which feeds the storage compartment when it is required. The system is controlled by a timer and a thermometer, which together balance the need for refrigeration against the need to switch the system on/off. To aid storage of cold in the cold store, the system includes a heat exchange unit so that a fluid with better heat storing characteristics can be used in the cold store. A cold storing material may be also be located in the top of the storage compartment to dampen any fluctuations in the temperature of the storage compartment.

Title: Method of fabricating an aluminium plug using selective chemical vapour        deposition
Inventor: SUN SHI-CHUNG
IPC: H01L21/285
Filed: 1996-12-04
Abstract: An improved method of fabricating an aluminum plug using a selective chemical vapor deposition (CVD) procedure. A semiconductor component is first formed in a substrate having an insulating layer formed over the surface thereof. The insulating layer has a contact opening formed therein that exposes a conductive region of the semiconductor component. Then, a vacuum thermal annealing treatment is performed on the device substrate. Dimethylethylamine alane (DMEAA) is used as a precursor for then depositing an aluminum layer over the surface of the substrate, using a CVD procedure performed at a substrate temperature not exceeding 250 ‹C, for fabricating an aluminum plug in the contact opening. The aluminum plug is selectively deposited over the surface of the exposed conductive region, while relatively not deposited over the surface of the insulating layer.
